Physicists develop world’s best qubits
A team of researchers at UCLA has set a new record for preparing and measuring the quantum bits, or qubits, inside of a quantum computer without error. The techniques they have developed make it easier
Broken time-reversal symmetry in iron-based superconductors
Physicists at TU Dresden have discovered spontaneous static magnetic fields with broken time-reversal symmetry in a class of iron-based superconductors. This exceptional property calls for new theoretical models and may become important in quantum computing.
Quantum Hall effect in 3-D topological materials
Researchers have found surprising evidence that the quantum Hall effect exists in topological superconductors that could be used to build fault-tolerant quantum computers. The quantum Hall effect was first measured in two-dimensional materials. The study
Efficient detection of microwave photons
Researchers at the French National Center for Scientific Research (CNRS) demonstrate a new microwave-photon detection method that improves on existing techniques by yielding significantly fewer false positive detections. High-performance single-photon detectors work by transforming the
Quantum Computing at room temperature
US Army researchers became the first to demonstrate the feasibility of a quantum logic gate comprised of photonic circuits and optical crystals. Photonic circuits that incorporate nonlinear optical crystals have presently emerged as the sole
‘Hot and messy’ entanglement of 15 trillion atoms
When dealing with entanglement, current quantum technologies isolate the systems they work with and operate at temperatures close to absolute zero. In a recent experiment, the ICFO team, in contrast, heated a collection of atoms
KT sends 5G data with quantum cryptography
KT has made a field test success that encrypts and transmits 5G data with a quantum cryptographic communication technology developed in Korea. This test is the most basic step in launching a service with the
UK companies to build radically new operating system for quantum computers
A consortium led by Cambridge-based quantum computing software developer Riverlane has been awarded a £7.6M grant from the government’s Industrial Challenge Strategy Fund to deploy a highly innovative quantum operating system. The project will deliver an operating
Photon-assisted tunneling signatures in Majorana wires
Researchers at the University of Copenhagen and Microsoft Quantum Lab Copenhagen have recently carried out a study investigating the potential of Majorana zero modes, zero-energy quasiparticle states that can be found in superconductive hybrid nanowires,
QKD provides security in power grid
A team from the US Department of Energy’s Oak Ridge and Los Alamos national laboratories led a QKD demonstration in power grid hosted by EPB, a community-based utility and telecommunications company. Using an isolated portion
